Move Checker.enableAlias to Config.EnableAlias (for types2) and
Config._EnableAlias (for go/types), and adjust all uses.
Use Config.EnableAlias to control Alias creation for types2 and
with that remove dependencies on the gotypesalias GODEBUG setting
and problems during bootstrap. The only client is the compiler and
there we simply use the desired configuration; it is undesirable
for the compiler to be dependent on gotypesalias.
Use the gotypesalias GODEBUG setting to control Config._EnableAlias
for go/types (similar to before).
Adjust some related code. We plan to remove gotypesalias eventually
which will remove some of the new discrepancies between types2 and
go/types again.
Fixes#66874.

Currently, when a Transport creates a new connection for a request,
it uses the request's Context to make the Dial. If a request
times out or is canceled before a Dial completes, the Dial is
canceled.
Change this so that the lifetime of a Dial call is not bound
by the request that originated it.
This change avoids a scenario where a Transport can start and
then cancel many Dial calls in rapid succession:
- Request starts a Dial.
- A previous request completes, making its connection available.
- The new request uses the now-idle connection, and completes.
- The request Context is canceled, and the Dial is aborted.

This change defines two commonly-defined functions and a
commonly-defined type in internal/abi to try and deduplicate some
definitions. This is motivated by a follow-up CL which will want access
to TypeOf in yet another package.
There still exist duplicate definitions of all three of these things in
the runtime, and this CL doesn't try to handle that yet. There are far
too many uses in the runtime to handle manually in a way that feels
comfortable; automated refactoring will help.
For #62483.

The SSA rewrite pass has some logic that looks to see whether a
suspiciously large number of rewrites is happening, and if so, turns
on logic to try to detect rewrite cycles. The cycle detection logic is
quite expensive (hashes the entire function), meaning that for very
large functions we might get a successful compilation in a minute or
two with no cycle detection, but take a couple of hours once cycle
detection kicks in.
This patch moves from a fixed limit of 1000 iterations to a limit set
partially based on the size of the function (meaning that we'll wait
longer before turning cycle detection for a large func).
Fixes#66773.

This CL changes the interpretation of the unset value
of gotypesalias to not equal "0".
This is a port of CL 577715 from go/types to types2,
with adjustments to go/types to keep the source code
in sync. Specifically:
- Re-introduce testing of both modes (gotypesalias=0,
gotypesalias=1) in go/types.
- Re-introduce setting of gotypesalias in some of the
tests for explicit documentation in go/types.
The compiler still uses the (now) non-default setting
due to a panic with the default setting that needs to
be debugged.
Also, the type checkers still don't call IncNonDefault
when the non-default setting of gotypesalias is used.

In both the v1 and v2 cmd/trace, pprofMatchingGoroutines will generate
no output at all if the filter name passed to it is the empty string.
This is rather pointless because there are at least two places where we
don't pass a name to filter. Modify pprofMatchingGoroutines to include
*all* goroutines in the trace if the name to filter by is not specified.
For #66782.

Turns out we ported all the profile generation, but forgot to actually
support the command line flags for them! This change fixes the issue by
handling the different kinds of profiles and writing them out to stdout.

Currently TestGCStress' main loop allocates a randomly-sized byte slice
in a loop. On the windows-386 builder, it looks like the following is
happening.
In such heavily-allocating scenarios, the test seems to be able to
outrun the GC. This is a known issue on all platforms, but it looks to
me like there may be a real issue with mark termination. (Fixing that is
outside the scope of this change, but relevant here.)
Furthermore, while the test is ramping up, the pacer is taking time to
acclimate to the high allocation rate. This is probably made worse due
to the coarse time granularity on Windows, since the pacer relies on
accurate time measurements.
Because the pacer is ramping up, it isn't starting early enough, causing
a lot of memory to get allocated black and inflate the live heap size.
This happens for more than one cycle.
Last but not least, because the core allocating loop of this test
allocates randomly-sized byte slices, we could just get unlucky and
inflate the live heap by much more sometimes. Furthermore, the
randomness creates chaos for the pacer that is totally unnecessary for
this test.
Although I couldn't reproduce the issue we're seeing on the trybots in a
gomote, I *could* reproduce memory spikes in general. These memory
spikes always occurred before the pacer had a chance to "warm up," in
the first two cycles after the heavy allocating begins.
I believe the flakiness we're seeing is all of these factors lining up,
because if I just make the size of the allocated byte slices smaller and
non-random, I can no longer reproduce the memory spikes. This change
implements this as a fix in the hope that it'll resolve the flakiness.
Fixes#66624.

There is no hyphen between the organization and the number.
For example, https://standards.ieee.org/ieee/754/6210/
shows the string "IEEE 754-2019" and not "IEEE-754-2019".
This assists in searching for "IEEE 754" in documentation
and not missing those using "IEEE-754".

For Go 1.23, we decided to no longer support the old CLI interface
exposed by wasmtime. This removes the extra logic included to support
both the new and the old CLI interface. Now only versions of wasmtime
14 and newer are supported.

Use "slices.Equal" instead of "reflect.DeepEqual".
Replace unnecessary helper type "byIndex" with "slices.SortFunc".
